Auto-answer Modems and Answering Machines
ATA 2 can be connected to a modem or an answering machine as well as a
telephone. It can be programmed to ring in combination with a telephone connected
to one external line on the Business Communications Manager system. It can also
be designated as the Night Set to answer calls after hours. To assign an external line
to ring at a telephone connected to an ATA 2, contact your Installer or System
Administrator.
Modem and FAX Transmission Compatibility
ATA 2 is compatible with all commercial FAX and modem protocols. When
connected to ATA 2, the Business Communications Manager base unit supports
data transmission rates up to and including 28.8 kbit/s.
Note: The maximum data transmission rate is subject to the quality of the end-to-
end channel and cannot be guaranteed.
